(a) What is negative super elevation? A $1^{\circ}$ curve track diverges from a main curve of $3^{\circ}$ in the opposite direction in the layout of a BG track, calculate the super elevation and the speed on the branch line when the maximum speed permitted on the branch line is 36.5 kmph .

Explanation

Negative super elevation is a curve with a smaller radius than the main curve. The super elevation is the difference in elevation between the outer rail and the inner rail of a curve. The speed on the branch line can be calculated using the formula v = sqrt(2 * g * R * tan(θ)).
